Francis Bacon (1909 – 1992) was an Irish-born British figurative painter known for his raw, unsettling imagery. Focusing on the human form, his subjects included crucifixions, portraits of popes, self-portraits, and portraits of close friends, with abstracted figures sometimes isolated in geometrical structures. Rejecting various classifications of his work, Bacon said he strove to render "the brutality of fact." He built up a reputation as one of the giants of contemporary art with his unique style.
Bacon said that he saw images "in series", and his work, which number around 590 extant paintings along with many others he destroyed, typically focused on a single subject for sustained periods, often in triptych or diptych formats. His output can be broadly described as sequences or variations on single motifs; including the 1930s Picasso-influenced bio-morphs and Furies, the 1940s male heads isolated in rooms or geometric structures, the 1950s "screaming popes," the mid-to-late 1950s animals and lone figures, the early 1960s crucifixions, the mid-to-late 1960s portraits of friends, the 1970s self-portraits, and the cooler, more technical 1980s paintings.
